Question

Esther starts at one corner of a square field and walks 90 feet along one side to another corner of the field. She turns 90° and walks 70 feet, and then walks straight back to where she started.

What is the area of the part of the field she walked around?

Answer 1

This makes a right triangle so multiply 90 by 70 and divide it by 2.
You will get 3150

Answer 2
